Currently over twentymillion compounds have been reported in thechemical literature; about 90% of them areorganic, ie they contain carbon. The remainingcompounds are called inorganic and are formedfrom the other elements, of which there areabout 100. That carbon so dominatescompound formation is a result of the fact that itis almost unique in its ability to form longchains with other carbon atoms. [Carbon sneighbor in the periodic table, silicon, can dothis but rarely does.] These chains with onecarbon joined to a second and the secondjoined to a third, etc., can be branched, ie,chains of carbon atoms can be attached tocarbons in the original chain.
Organic chemistry is the chemistry of the compounds of carbon. Currently over twenty million compounds have been reported in the chemical literature; about 90% of them are organic, ie they contain carbon. The remaining compounds are called inorganic and are formed from the …
